I have selenium webdriver script, and i want to run the script in jenkins. how to configure in jenkins. what steps i need to fallow? i am new to jenkins, can any one tell me the step by step procedure to fallow.

Other option would be to go to Configure Jenkins -> Configure Plugins and install Hudson Seleniumhq plugin and use the build step provided by them when configuring the jenkins job.

You might also want to create a Post-build Action to show reports. If you install Selenium HTML report plugin from the aforementioned Manage Plugins page, you can then add 'Publish selenium report' Post-build step.
